The equation of a line is -2x+5y=-20.<br> What is the x-intercept of the line?

fomenos

The x intercept of the given line is (10, 0)

<h3>Finding the x intercept of a line</h3>

The x intercept of a line is the point where the line crosses the x-axis

It is the point where the value of y is zero

Given the equation of a line -2x+5y = -20

Substitute y = 0 into the equation

-2x +5(0) = -20

-2x = -20

x = 10

Hence the x intercept of the given line is (10, 0)

A statistics professor plans classes so carefully that the lengths of her classes are uniformly distributed between 50.0 and 60.

Artist 52 [7]

Answer: 0.0250

Step-by-step explanation:

Given : A statistics professor plans classes so carefully that the lengths of her classes are uniformly distributed between 50.0 and 60.0 minutes.

We know that the uniform distribution is also known as rectangular distribution.

Density function for uniform distribution : $f(x)=\dfrac{1}{b-a}$

$=\dfrac{1}{60-50}=\dfrac{1}{10}$

Now, the probability that a given class period runs between 51.25 and 51.5 minutes :-

$\int^{51.5}_{51.25}f(x)\ d(x)\\\\ \int^{51.5}_{51.25}\dfrac{1}{10}\ dx\\\\=\dfrac{1}{10} [x]^{51.5}_{51.25}\\\\=\dfrac{1}{10}(51.5-51.25)=0.0250$

Hence, the probability that a given class period runs between 51.25 and 51.5 minutes = 0.0250
